They will have a spending advantage over the clubs outside the CL anyway. And then their 15% extra will be very different to say Brentford's 15%, because of their naturally higher revenue. While on the face of it, it helps those clubs outside the CL places, it does favour the bigger clubs a lot more, and helps ensure they don't stay out of it for too long.
Well timed, with their PSR compliance iffy at the moment. How lucky for Liverpool too, PSR getting scrapped the end of the summer they go and spend 500m in. A year ago the PL were happy to go to court with us over their rules. Now, they need to be 'improved' suddenly.
